Jaundice in the intensive care unit.

Area of Science:

• Critical Care Medicine
• Hepatology
• Internal Medicine

Background:

• Hyperbilirubinemia, or jaundice, is a frequent complication in intensive care units (ICUs), affecting up to 40% of critically ill patients.
• The etiology of jaundice in the ICU is often complex and multifactorial, presenting a significant diagnostic challenge for physicians.

Purpose of the Study:

• To review the common causes and diagnostic considerations of acute jaundice in the ICU setting.
• To emphasize the importance of stratifying jaundice into obstructive and nonobstructive categories for guiding management.

Main Methods:

• Review of existing literature on hyperbilirubinemia in critically ill patients.
• Clinical discussion of potential etiologies including sepsis, multisystem organ failure, shock liver, heart failure, hemolysis, and drug toxicity.

Main Results:

• Jaundice in the ICU can be indicative of serious underlying conditions such as sepsis, multisystem organ failure (MSOF), or shock liver.
• Potential causes include right-sided heart failure, red blood cell breakdown, and adverse drug reactions.

Conclusions:

• Acute jaundice in the ICU requires careful evaluation due to its diverse and potentially serious causes.
• Classifying jaundice as obstructive or nonobstructive is a crucial first step in directing appropriate diagnostic and therapeutic interventions.
